경련을 주소로 내원하여 뇌혈류 SPECT와 MRI 또는 CT, 뇌파도가 시행되었던 115명을 대상으로 경련의 원인과 뇌혈류 SPECT의 유형을 비교하고자 하였다. 대상환자 115명중 28명이 기질적인 원인에 의한 경련이었으며 42명이 전신성 경련, 45명이 부분적 발작이었다. 전신성 경련환자의 뇌혈류 SPECT 유형은 22명이 정상이었고 8명이 미만성의 혈류감소, 4명이 전두엽, 5명이 측두엽, 3명이 전두엽과 측두엽에 걸친 혈류감소를 보였다. 부분적 발작환자 54명중 19명이 뇌파도와 일치하는 부위에 혈류감소를 보였다. 결론적으로 간질 발작간의 뇌혈류 SPECT는 기질적인 원인을 비교적 예민하게 찾을 수 있었고, 전신성 경련환자에서는 정상이거나 육안적으로 경미한 정도의 전두엽 또는 측두엽의 혈류감소를 보였다. 이러한 혈류 감소가 전신성 경련환자와 부분적 발작 환자에서 인지기능이나 항경련제 등과의 연관성에 대해서는 더욱 연구가 되어야 할 것이다.

Objective: The SAFARI score was introduced to assess the risk of convulsive seizure during admission for aneurysmal subarachnoid hemorrhage in 2017. This study was conducted to determine whether the SAFARI score derived from the afore-mentioned study could be applied to patients with aneurysmal subarachnoid hemorrhage in Korea. Methods: We conducted a retrospective study of patients who were diagnosed with aneurysmal subarachnoid hemorrhage from March 2013 to October 2017. Patients' age, sex, blood pressure, pulse rate, body temperature, Glasgow-Coma Scale, Hunt-Hess scale, modified Fisher grade, size of ruptured aneurysm, surgery type, transfusion, and SAFARI score were compared between the seizure and non-seizure groups. The area under the receiver operator characteristic curves was calculated to evaluate the predictive ability for seizure during admission. Logistic regression analysis was used to analyze predictive factors for seizure during admission. Results: A total of 220 patients were included. Ninety-seven (44.1%) were male and 123 (55.9%) were female. The mean age of the patients was 65.8 years old (range, 56-75). The area under the curve of the SAFARI score for predicting seizure was 0.813. The SAFARI score was the only significant predictor of seizure during admission, while other factors were not statistically significant upon logistic regression analysis. Conclusion: The SAFARI score could be used for predicting seizure during admission in patients with aneurysmal subarachnoid hemorrhage.

Epilepsy is a neurological condition that from time to time produces brief disturbances in the normal electrical functions of the brain, Normal brain function is made possible by millions of tiny electrical charges passing between nerve cells in the brain and to all parts of the body. They may affect a person's consciousness, bodily movements or sensations for a short time. These physical changes are called epileptic seizures. These clinical data, gathered an epileptic seizure whose main symptom was convulsion, was analyzed. This clinical report pertains to a 51 year-old man who suffered an epileptic seizure and after effects of weakness. He was treated with ChongsimOndamTang(淸心溫膽湯). The cheif symptom, epileptic seizure, disappeared and general conditions improved after Korean medical treatments, so this is reported as a potential treatment.

Burns due to epileptic seizures are commonly deep and usually require operative treatment. The purpose of this study is to identify the characteristics of burned epileptic patients that could lead to the development of preventive programs to reduce the incidence of burn injuries. We analyzed epidemiological data for 34 patients acutely burned due to epileptic seizure admitted retrospectively. There were 15 male and 19 female subjects. The age distribution was from 6 years to 70 years with the mean age of 42.7 years. Seizures usually occurred while carrying out daily domestic chores. Scalding burns were the most common(38.2%) and most burns were above deep second degree(94.1%). The most common seizure type was generalized tonic-clonic, followed by absence and complex partial. The seizure mostly occurred in the morning because the therapeutic blood level of antiepileptic drugs was decreased extremely at that time by stopping drug arbitrarily or taking inadequately. So more frequent follow-ups at the neurology outpatient clinics for epileptics should be strictly reinforced to maintain the adequate therapeutic blood levels of antiepileptic drugs and fire protective implements should be prepared in the house.

The features of seizure-related brain injuries in rats poisoned i.p. with diisopropylfiuorophosphate were investigated. Pyridostigmine bromide (0.1 mg/kg) and atropine methylnitrate (20 mg/kg), which are centrally inactive, were pretreated i.m. 30 min and 10 min, respectively. before diisopropylfluorophosphate (10 mg /kg, $2LD_50$) poisoning to reduce the mortality and eliminate peripheral signs. Diisopropylfluorophosphate induced severe limbic seizures, and early necrotic and delayed apoptotic brain injuries. The necrotic brain injury, which was closely related to seizure intensity, was exerted as early as 1 hr predominently in hippocampus and piriform cortex. showing spongiform change (malacia) of neurophils in severe cases, in contrast to a typical apoptotic (TUNEL-positive)pattern after 12 hr in thalamus, and a mixed type in amygdala. Nitric oxide content in cerebrospinal fiuid significantly increased after 2 hr, reaching a maximal level at 6 hr. Pretreatment with $_L-N^G$-nitroarginine, an inhibitor of nitric oxide synthase, reduced nitric oxide content and attenuated only apoptotic brain injury in all four brain regions examined without affecting seizure intensity and necrotic injury. Taken together, early necrotic and delayed apoptotic brain injuries induced by diisopropylfiuorophosphate poisoning in rats may be related to seizure intensity and nitric oxide production, respectively.

Objectives The purpose of this study is to report a case of one infant patient diagnosed as Sik-Gan (食癎) who was treated by Korean medical treatment. Methods We diagnosed an infant patient as Sik-Gan (食癎) and treated him with herbal medicine, acupuncture, moxa and chuna therapy while correcting his eating habit. To measure the degree of the patient's progress, the frequency and exact symptoms of seizure events, and gastrointestinal symptoms were recorded. Results Korean medical treatment reduced the patient's the frequency of seizure, and improved gastrointestinal symptoms. Conclusions A patient who has past medical history of epileptic seizures, unhealthy eating habits and gastrointestinal malfunctions is prone to have a specific form of seizure called the Sik-Gan (食癎). In this report, we have proven that variety of Korean medical treatment can considerably be effective in preventing recurring seizure events and improving the patients' gastrointestinal symptoms.

Low-grade epilepsy-associated neuroepithelial tumors (LEATs) are responsible for drug-resistant chronic focal epilepsy, and are the second-most common reason for epilepsy surgery in children. LEATs are extremely responsive to surgical treatment, and therefore epilepsy surgery should be considered as a treatment option for LEATs. However, the optimal time for surgery remains controversial, and surgeries are often delayed. In this review, we reviewed published article on the factors associated with seizure and cognitive outcomes after epilepsy surgery for LEATs in children to help clinicians in their decision whether to pursue epilepsy surgery for LEATs. The achievement of gross total resection may be the most important prognostic factor for seizure freedom. A shorter duration of epilepsy, a younger age at surgery, and extended resection of temporal lobe tumors have also been suggested as favorable prognostic factors in terms of seizure control. Poor cognitive function in children with LEATs is associated with a longer duration of epilepsy and a younger age at seizure onset.

Planaria were recently reported to be a simple and sensitive model to investigate the mechanistic aspect of seizure and to screen potential anticonvulsants. Using planarian model, we analyzed the pharmacological effect of ukgansan (UGS), an oriental herbal medicine containing seven medicinal herbs, on the planarian locomotor velocity (pLMV) and glutamate-induced seizure-like activity (pSLA). To test whether D. japonica is suitable for studying anti-seizure agents, we investigated the effect of glutamate on pLMV and pSLA in D. japonica. In the present study we first confirmed that pSLA in D. japonica was induced by L-glutamate. Glutamate significantly produced pSLA in a dose dependent manner, but did not affect pLMV. These glutamate-induced paroxysms were decreased by antiepileptic drug, topiramate. A similar inhibitory effect on glutamate-induced pSLA was observed after the treatment of UGS. The present results suggest that UGS and its active constituents possess useful substance inhibiting seizure in planarian and that D. japonica provides a convenient model to search active herbs containing anti-seizure activity.

Long-term electroencephalography (EEG) monitoring is time-consuming, and requires experts to interpret EEG signals to detect seizures in patients. In this paper, we propose a novel automated method called adaptive slope of wavelet coefficient counts over various thresholds (ASCOT) to classify patient episodes as seizure waveforms. ASCOT involves extracting the feature matrix by calculating the mean slope of wavelet coefficient counts over various thresholds in each frequency subband. We validated our method using our own database and a public database to avoid overtuning. The experimental results show that the proposed method achieved a reliable and promising accuracy in both our own database (98.93%) and the public database (99.78%). Finally, we evaluated the performance of the method considering various window sizes. In conclusion, the proposed method achieved a reliable seizure detection performance with a short-term window size. Therefore, our method can be utilized to interpret long-term EEG results and detect momentary seizure waveforms in diagnostic systems.
